Definitions

  • the present invention is in the field of automated picking. It relates to a method and a device for the automated handling and conveyance of a suspension element, such as a carrier bag.
  • online supermarkets are also increasingly establishing themselves, which present themselves as an alternative to conventional supermarkets and accordingly also offer a range that is usual for supermarkets, such as Food, personal care items, household items, stationery, etc.
  • One advantage of the online supermarket is that the customer can put together their purchases from home or on the go via an online portal and have them delivered to their home or to a collection point via a delivery service.
  • the ordered goods are delivered in suspension devices, such as carrier bags, as are also available in conventional supermarkets for packing the purchases at the cash registers.
  • the tote bags are usually flat folded tote bags, which have to be opened and unfolded before being filled with the purchases.
  • the order picking of the ordered goods in the suspension means is usually carried out in automated logistics centers.
  • the carrying means such as carrying bags
  • the carrying means are generally durable and have an appropriate tear resistance, they are often not robust enough to be conveyed as a transport or transport container for order picking along a picking route.
  • the publication script WO 2016/197176 A1 describes a method for picking goods into sacks.
  • the bags are placed in box-shaped loading and transport aids for order picking.
  • the loading and transport aids support the bags to the side and to the floor, thus reducing the risk of damage to the bags, for example when the bags are filled with goods.
  • Keep-open means ensure that the sacks remain open during order picking or do not collapse again.
  • the carrying means such as carrying bags, are usually opened manually according to the state of the art and introduced into the loading and transport aids.
